A wicked counter-right hook from Andy Lee may have punched his ticket to a future showdown with Gennady Golovkin as he won the vacant WBO middleweight title against Matt Korobov on the Tim Bradley-Diego Chaves undercard.

Matt Korobov says he’s not looking past Andy Lee, who he fights for the vacant WBO middleweight belt on Saturday on HBO, but the former Russian amateur standout wants to avenge an amateur loss to Gennady Golovkin.

The Dec. 13 Tim Bradley-Diego Chaves fight could headline a HBO-televised tripleheader from the Cosmopolitan in Las Vegas. Mauricio Herrera-Jose Benavides Jr. and Andy Lee-Matt Korobov are the other two bouts to be added to the show.

A deal is in place for a Dec. 13 battle between Matt Korobov and Andy Lee for the WBO’s vacant middleweight title, Top Rank CEO Bob Arum informed RingTV.com on Monday. The card is being promoted by Frank Warren and will take place in Ireland.

WBO junior middleweight beltholder Demetrius Andrade has decided to defend his belt in December, a change of heart that comes less than three weeks after successfully convincing the organization to order a fight between himself and Matt Korobov for its vacant middleweight title.

The WBO ordered its 154-pound beltholder Demetrius Andrade to fight Matt Korobov for the middleweight belt vacated last week by Peter Quillin. The decision didn’t sit well with Korobov’s promoter Bob Arum, who is upset with Andrade’s co-promoter Artie Pelullo.

Not letting the peculiar nature of Peter Quillin vacating the WBO middleweight title take hold, Top Rank Promotions’ Bob Arum is making moves to promote Matt Korobov vs. Billy Joe Saunders for the belt.

Undefeated middleweight Peter Quillin announced on social media that he is vacating his WBO title, effectively pulling himself out of his scheduled Nov. 1 bout against mandatory challenger Matt Korobov.
